Tech Xplore / 'Artificial leaf' generates clean hydrogen from contaminated seawater
Scientists from Nanyang Technological University, Singapore, have designed a device that harvests sunlight to generate clean hydrogen from seawater and simultaneously degrades hydrazine, a highly toxic contaminant from industrial ...
Phys.org / Robotic lab sets up and runs optics experiments on demand
Every new generation of phone display, television screen and solar panel is the result of precision optics experiments, which use lasers and other light sources to measure the optical properties of candidate materials. These ...
Medical Xpress / Anti-seizure drug fights aggressive childhood brain tumors, study shows
An existing anti-seizure drug slows the growth of a devastating group of childhood cancers, new Stanford Medicine-led research has shown. The tumors, called diffuse midline gliomas, strike the brain and spinal cord. They ...
Phys.org / Nearly 50 'ghost galaxies' emerge around three hosts, challenging dwarf galaxy counts
Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been ...
Phys.org / Without bacteria or chemicals: How methanol and formaldehyde form abiotically in nature
The biopolymer lignin—one of the most important carbon reservoirs in plants and soils—not only decays through fungi or bacteria but can also be chemically attacked by iron linked to reactive oxygen species, without the involvement ...
Phys.org / Half-billion-year-old fossils rewrite the origin story of starfish
Scientists have discovered several 518-million-year-old fossils that reshape understanding of the origins of the animal group containing starfish. The fossils show that these animals ate using tentacles rather than passively ...
Medical Xpress / Scientists map brain's mysterious 'blue place' and discover longest neuron ever measured in a mouse
Deep in the brainstem sits a small but important cluster of neurons known as the locus coeruleus (LC), Latin for "blue place." It makes up a tiny fraction of the brain's cells but plays an important role by releasing the ...
Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals
To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...
Phys.org / Ancient DNA traces medieval migration from Sweden to Finland
A new study led by the University of Turku provides new insights into the population history of Finland during the Late Iron Age and the Middle Ages. The researchers analyzed the genomes of people who lived in southwestern ...
Phys.org / Threatened bumblebee populations in England and Wales face severe genetic declines
A new study reveals that an important pollinator is rapidly losing genetic diversity in Britain. Moss carder bumblebees were once widespread across the UK, living in flower-rich meadows, marshes and heathlands, where they ...
Phys.org / New method reveals how virus particles can build themselves, molecule by molecule
Oxford University researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The results were ...
Tech Xplore / A robot that shifts its own weight to cross land, steps, and water
A robot meant to inspect a coastline, a flooded street or a wetland can't count on one kind of ground. It might need to crawl over a hard surface, climb a bank, scale a curb or a step, then slide into open water, often within ...
